Surface enhanced Raman scattering of pyridazine molecule:absorption configuration and enhancementmechanism via bond polarizabilities
哒嗪分子表面增强拉曼效应下键极化率的研究:吸附构型与增强机理

The temporal molecular bond polarizabilities of pyridazine molecule absorbed on Ag electrode were explored from its surface enhanced Raman intensities, showing that the two nitrogen atoms are the absorption sites and the enhancement is dominated by the charge transfer mechanism. The behaviors of the charges on the skeletal bonds were demonstrated under various applied voltages, which shows the conjugation effect. This algorithm is universal for the surface systems as long as their Raman spectra are available.
